Clunking In Front End

[99silverado1500]

I did search, and didnt find anything on what my truck is doing. When I hit the brakes, it makes a pretty wierd clunk/pop noise, and it does it like 5 times until stopped. I only notice it from 5-0 Mph. It sometimes does it starting out, and it will do it every now and then over a bump. Its not the steering shaft clunk, I can hear this in the cab from the front. Is this ball joints? Its a quick set of clunks. I dont really notice it turning so much so im not sure if its ball joints or what it is. I thought it was the brake pistons at first so I lubed them up, but it still does it, and it will creak, clunk pop, its annoying and im getting tired of hearing it, any insight?

Only thing that comes to my mind is ball joints..........
